Yes, I can reproduce it reliable. But I use 3-nodes ($redundance=3)
I can get it working by introducing a sleep(5) after auto_deploy:
--------------
my ($rc, $res) = $hdl->create_resource($name, {});
check_drbd_rc($rc->[0]);
($rc, $res) = $hdl->create_volume($name, $size, {});
check_drbd_rc($rc->[0]);
my $redundancy = get_redundancy($scfg);;
($rc, $res) = $hdl->auto_deploy($name, $redundancy, 0, 0);
check_drbd_rc($rc->[0]);
sleep(5); # else we get split brain?!
($rc, $res) = $hdl->set_drbdsetup_props(
{
target => "resource",
resource => $name,
type => 'neto',
'allow-two-primaries' => 'yes',
});
check_drbd_rc($rc->[0]);
